## Summary

We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-710A1-10, - 710A2-20, and -710C4-11 turbofan engines. This proposed AD was prompted by a seized low-pressure turbine (LPT) fuel shut-off pawl carrier caused by corrosion of the pawl carrier pivot pin. This proposed AD would require removing the pawl carrier pivot pins, part number (P/N) BRR17117, from service and replacing them with parts eligible for installation. We are proposing this AD to prevent failure of the fuel shut-off mechanism, uncontained part release, damage to the engine, and damage to the airplane.
